The <EM>ic_sets</EM> library is a solver for constraints over the domain
of finite sets of integers.
Modelling with sets is useful for problems where one is not
interested in each item as a specific individual, but in a
collection of item where no specific distinction is made and thus
where symmetries among the element values need to be avoided.<BR>
